Being able to choose the right aperture is very vital for a photographer because the aperture basically camera aperaturecontrols a lot of different elements within a picture. But first of all, let’s start with a definition of what “aperture” means.

Since a camera’s function is to mainly gather light, there should be sort of a filter in which the light passes through. This is the aperture of a lens. The lens aperture is the opening of the lens in which light passes through. It can be controlled and managed by the one taking the photograph. One has to remember that the larger the diameter of the aperture, the more light it is able to pass through. The more light it allows to pass through, the brighter the image will become. Conversely, the smaller the diameter of the aperture is set, the darker the photograph will be.

The aperture is measured in f-stops. Examples of these are f/2.8, f/3.5, f/4.0 and so on and so forth. The photographer has to remember that the smaller the f-stop number or value, then larger the lens opening or the larger the aperture. Therefore, the aperture value is inversely proportional to the size of the opening it has. For example, when you have your lens set to the aperture setting of f/1.8, then that means that more light is allowed to go in. When the aperture is set to a higher value, such as f/22, the less light it allows to go in.

Another thing that you should know about aperture values is it also controls the depth of field or DoF. The depth of field is the distance where your subjects are in focus. Let’s say you’re aiming at a flower in your garden and you want the background of the flower to be blurred, you are then aiming for a shallow depth of field which means that there is a small or shallow distance wherein objects are in focus. You would want to use an aperture with a large opening If let’s say, you desire to capture an image which has the foreground and background in crisp focus, you then aim for an aperture which will give you greater depth of field such as f/22.

So, how does one go about choosing the right aperture? It all boils down to what type of picture you want to take: whether it is against a blurred background or whether it is taken under the noonday sun or indoors with intimate lighting, you should be able to adjust the aperture accordingly to suit your needs as a photographer.
